Sometimes your iPhone might refuse to even turn on after you have installed the latest iOS update.

However, no matter how intimidating it might seem, there sure are ways to remedy the issue and get your iPhone back up and running in no time.

Just follow the steps mentioned below.

What are the risks of updating the iOS?

The above questions would be more relevant to you if you are running an older iPhone.

That's because the more recent iOS updates are so designed to ensure the iPhone remain active for longer duration.

Apple said it is a deliberate ploy to keep older batteries running longer, even if that comes at the cost of performance.

That led to the infamous battery-gate scandal in 2016 wherein Apple was accused of slowing down iPhone 6 and 7 models.

The Cupertino company had later agreed to a $113m court mediated settlement. Besides, it had also offered affected users new batteries at subsidized rates as a goodwill gesture.

However, as a general rule of thumb, owners of iPhone 8 or older devices perhaps should best avoid the iOS 11 update.

Why won’t my iPhone turn on after update?

While it isn't too uncommon for iPhone devices to not turn on post an update, there are several reasons that causes the phenomenon. Here we discuss the more common among those.

1. Battery gone dead

Usually, the update process itself is quite power intensive and drains the battery quickly.

Things just doesn't stop once the update is downloaded and installed as there are a lot of things that goes on behind the scenes for the update to settle down. That too drains a lot of battery.

In the end, the entire update cycle usually leaves the battery exasperated and gasping for breath, if not dead already. So, plug into the mains and see if that isn't the issue.

2. iOS getting crashed

Software anomalies could be another reason for your iPhone not turning on or getting stuck on the Apple logo display.

A force restart is often the best thing to do in such a scenario.

3. Damaged firmware

A damaged firmware is often the reason for your iPhone not turning on, and it is quite common for firmware to get damaged during the updating process if things go wrong.

4. Hardware issue

A malfunctioning internal component too can prevent the iPhone from turning on.

In the unfortunate scenario of that happening, a visit to the nearest service center is the recommended thing to do, unless you have the requisite skills for the same.

Troubleshooting an iPhone that won't turn on after an iOS update

1. Charge the device

Downloading an iOS update can be a battery intensive process. So, make sure your iPhone has adequate charge before proceeding to update.

However, ensure you use the right lightning cable and adapter for charging as unauthorised accessories can end up damaging your iPhone in the long run.

The display should be showing only the battery which is an indication of the cable being connected properly.

Else, there is going to be an image of the battery as well as the charging cable which points to something being amiss and that the iPhone is not getting charged.

Also, keep the iPhone plugged in for at least 30 mins before attempting an update.
